Find the equation of the line given the following points (0,0) and (1,4). Calculate the gradient.

Fomula ya gradient $m$ ni:

$$m = \frac{y_2 - y_1}{x_2 - x_1}$$

Tumia pointi $(x_1, y_1) = (0,0)$ na $(x_2, y_2) = (1,4)$.

$$m = \frac{4 - 0}{1 - 0}$$ $$m = \frac{4}{1}$$ $$m = 4$$

Gradient ni $\boxed{4}$.

Tunatumia fomula ya mlinganyo wa mstari $y - y_1 = m(x - x_1)$.
Tumia gradient $m=4$ na pointi $(x_1, y_1) = (0,0)$.

$$y - 0 = 4(x - 0)$$ $$y = 4x$$

Mlinganyo wa mstari ni $\boxed{y = 4x}$.
